Brooks, Marshall doubtful

Linebackers Ahmad Brooks and Lemar Marshall are doubtful for the Sunday game at Seattle with groin injuries. Center Eric Ghiaciuc (thumb) is doubtful, too, and none of the three players practiced today.

With Brooks and Marshall possibly out -- Marshall has a better chance of playing -- the Bengals would be down to four healthy linebackers: Landon Johnson, Caleb Miller, Anthony Schlegel and Dhani Jones.

The Bengals could use a lot of "dime" defense, with three safeties and two cornerbacks on the field, and just two linebackers. Losing Brooks would seriously hurt the Bengals' run defense.

Asked about his linebackers after practice, head coach Marvin Lewis said, "We're fine."

He did concede, though, when it was pointed out that a player who doesn't practice all week -- Brooks -- normally don't play, Lewis said, "That's a good assumption."

Players, coaches and other team personnel are going through security right now at Paul Brown Stadium before loading charter buses to the airport for the flight to Seattle.

The team practiced inside Paul Brown Stadium at noon. Special teams coach Darrin Simmons rounded up players in the locker room to watch a quick loop of film from the practice.

Listed as questionable on the injury report today are offensive tackle Willie Anderson (heel), wide receiver Antonio Chatman (hamstring) and safety Chinedum Ndukwe (hamstring). They were limited in practice.

Probable are safety Dexter Jackson (back), wide receiver T.J. Houshmandzadeh (knee), cornerback Deltha O'Neal (knee) and defensive linemen Frostee Rucker (hamstring) and Bryan Robinson (foot). All of the players listed as probable practiced fully, except Robinson, who was limited.
